Description

Technical Field

[0001] This utility model relates to the field of motor assembly technology, specifically a motor rotor assembly guide device. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. A permanent magnet motor is a type of electric motor. A permanent magnet motor uses permanent magnets to generate a magnetic field, and its rotor speed is synchronized with the frequency of the current in the stator windings. Permanent magnet motors are a widely used type of motor, offering advantages such as high efficiency, good dynamic response, and low noise. They are widely used in electric vehicles, robotics, and other fields requiring high efficiency, high dynamic performance, and low noise.

[0003] During the assembly of existing permanent magnet motor rotors, the presence of magnets inside the motor causes the rotor to easily shift due to the magnetic force of the permanent magnets, resulting in improper assembly and low assembly efficiency.

[0004] Therefore, this utility model provides a motor rotor assembly guide device to solve the above problems. Utility Model Content

[0005] This utility model provides a motor rotor assembly guide device, which aims to solve the problems mentioned in the background art, such as the rotor of the existing permanent magnet motor being prone to misalignment during installation due to the magnetic force of the permanent magnet due to the magnets inside the permanent magnet motor, resulting in the rotor being unable to be assembled properly and causing low assembly efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a motor rotor assembly guide device, comprising a base plate, on which a clamping structure and a guide structure are mounted, and a cylinder is mounted on the guide structure;

[0007] The clamping structure includes a first motor installed on the side wall of the base plate and a bidirectional lead screw set at the drive end of the first motor. L-shaped plates are threadedly installed on the left and right sides of the bidirectional lead screw, and an arc-shaped clamping plate is installed at the other end of the L-shaped plate.

[0008] The guiding structure includes a support frame mounted on the end face of the base plate. A screw is rotatably mounted on the bottom of the support frame's inner cavity via bearings, and a top plate is located on the upper end of the support frame. A lifting plate and a second motor are threaded onto the screw. A guide cylinder is mounted on the front end of the lifting plate. By setting up the clamping and guiding structures, the motor housing is fixed by two sets of arc-shaped clamps moving close together. Then, the lifting plate drives the guide cylinder to move down to the upper end of the stator, placing the rotor inside the guide cylinder. The cylinder extends downwards, pushing the rotor into the stator, achieving rapid rotor assembly. This solves the problem of rotor misalignment during assembly in existing permanent magnet motors due to the magnetic force of the permanent magnets, preventing proper rotor assembly and improving the assembly efficiency of the motor rotor.

[0009] Preferably, a buffer structure is installed at the drive end of the cylinder;

[0010] The buffer structure includes a mounting post installed at the lower end of the buffer structure. A buffer spring is mounted on the mounting post through an annular groove. A sliding cylinder is provided at the lower end of the buffer spring, and a pressure plate is installed at the lower end of the sliding cylinder.

[0011] Preferably, the bottom of the base plate is equipped with a support leg, the bottom of the support leg is equipped with a rubber pad, the clamping structure is provided with a motor housing, and the inner wall of the motor housing is equipped with a stator.

[0012] Preferably, the right end of the base plate is rotatably connected to the end of the bidirectional lead screw away from the first motor via a bearing, and a sliding groove is provided on the base plate corresponding to the bidirectional lead screw, and the base plate is slidably connected to the L-shaped plate through the sliding groove.

[0013] Preferably, the upper end of the screw passes through the top plate, the second motor is connected to the end face of the top plate by bolts, the top plate has a through hole, and the driving end of the cylinder passes through the through hole.

[0015] Beneficial effects: By setting up a clamping structure and a guiding structure, the motor housing is fixed by the two sets of arc-shaped clamps on the left and right sides approaching each other. Then, the lifting plate drives the guide cylinder to move down to the upper end of the stator, placing the rotor inside the guide cylinder. The cylinder extends the drive rod downward to push the rotor into the interior of the stator, realizing the function of rapid rotor assembly. This solves the problem that the rotor of the existing permanent magnet motor is prone to displacement during installation due to the magnetic force of the permanent magnet, which makes it impossible to assemble the rotor normally. This improves the assembly efficiency of the motor rotor. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] This embodiment provides a motor rotor assembly guide device, such as... Figure 1-4 As shown, the assembly guide device includes a base plate 1, a clamping structure 2 and a guide structure 3 mounted on the base plate 1, and a cylinder 4 mounted on the guide structure 3.

[0024] The clamping structure 2 includes a first motor 21 installed on the side wall of the base plate 1 and a bidirectional lead screw 22 set at the drive end of the first motor 21. L-shaped plates 23 are threadedly installed on the left and right sides of the bidirectional lead screw 22, and an arc-shaped clamping plate 24 is installed at the other end of the L-shaped plate 23.

[0025] The guide structure 3 includes a support frame 31 installed on the end face of the base plate 1. A screw 32 is rotatably installed at the bottom of the inner cavity of the support frame 31 via a bearing, and a top plate 33 is set at the upper end of the support frame 31. A lifting plate 34 is threadedly installed on the screw 32, and a second motor 35 is set at the upper end of the screw 32. A guide cylinder 36 is installed at the front end of the lifting plate 34.

[0026] In use, the motor housing 7 is placed on the end face of the base plate 1, positioned between the two sets of arc-shaped clamping plates 24. The first motor 21 is driven to rotate forward via the control panel. The first motor 21 drives the bidirectional lead screw 22 to rotate, which in turn drives the two sets of left and right L-shaped plates 23 to move synchronously closer. The L-shaped plates 23 move the arc-shaped clamping plates 24, thus bringing the two sets of arc-shaped clamping plates 24 closer together to clamp and fix the motor housing 7. Then, the second motor 35 is started to rotate forward, driving the screw 32 to rotate synchronously. The screw 32 drives the lifting plate 34 to move downwards. 4. Drive the guide cylinder 36 downward and make its lower end contact the upper end of the stator 8. Then, put the rotor into the interior of the guide cylinder 36 from the upper port. Finally, start the cylinder 4 to extend downward through the control panel. The cylinder 4 drive rod pushes the motor shaft downward to move. The motor shaft carries the rotor into the interior of the stator 8, realizing the function of quick assembly of the rotor. This solves the problem that the rotor of the existing permanent magnet motor is prone to displacement during installation due to the magnetic force of the permanent magnet, which makes it impossible to assemble the rotor normally. This improves the assembly efficiency of the motor rotor.

[0027] In this embodiment, a support leg 5 is installed at the bottom of the base plate 1, and a rubber pad is installed at the bottom of the support leg 5. A motor housing 7 is provided on the clamping structure 2, and a stator 8 is installed on the inner wall of the motor housing 7. The right end of the base plate 1 is rotatably connected to the end of the bidirectional lead screw 22 away from the first motor 21 through a bearing. A sliding groove 11 is provided on the base plate 1 and corresponding to the bidirectional lead screw 22. The base plate 1 is slidably connected to the L-shaped plate 23 through the sliding groove 11.

[0028] Among them, the bottom of the support leg 5 is equipped with a rubber pad, and the support leg 5 contacts the bearing surface through the rubber pad, which can increase the contact friction between the support leg 5 and the bearing surface, so that the assembly guide device will not easily slip, thus improving the placement stability of the assembly guide device.

[0029] In this embodiment, the upper end of the screw 32 passes through the top plate 33, and the second motor 35 is connected to the end face of the top plate 33 by bolts. The top plate 33 has a through hole 331, and the driving end of the cylinder 4 passes through the through hole 331.

[0030] The through hole 331 allows the drive rod of the cylinder 4 to pass through and extend to the bottom of the top plate 33, thereby pushing the rotor into the stator 8 and installing the rotor.

[0031] Example 2

[0032] Unlike Embodiment 1, the drive end of cylinder 4 is equipped with a buffer structure 6;

[0033] The buffer structure 6 includes a mounting post 61 installed at the lower end of the buffer structure 6. A buffer spring 62 is installed on the mounting post 61 through an annular groove 611. A slide cylinder 63 is provided at the lower end of the buffer spring 62. A pressure plate 64 is installed at the lower end of the slide cylinder 63.

[0034] In use, the drive rod of cylinder 4 is activated via the control panel to extend downwards. The drive rod of cylinder 4 moves the buffer structure 6 downwards, causing the bottom of the pressure plate 64 to contact the upper end of the motor shaft. With the assistance of the motor shaft, the pressure plate 64 is pushed upwards. The pressure plate 64 drives the slide cylinder 63 to move into the annular groove 611 and compress the buffer spring 62, thereby buffering the instantaneous collision force between the pressure plate 64 and the motor shaft. This prevents damage to the motor shaft due to excessive collision force, thus protecting the motor shaft during the assembly process. When the pressure plate 64 contacts the lower end of the mounting column 61, the mounting column 61 drives the pressure plate 64 to continue moving downwards, pushing the motor shaft. The motor shaft, carrying the rotor, enters the stator 8 for assembly, thus improving the performance of the assembly guide device.

[0035] In this embodiment, the mounting post 61 is slidably connected to the slide cylinder 63 through the annular groove 611. The upper outer wall of the slide cylinder 63 is provided with a limiting platform 631. The mounting post 61 is provided with a limiting groove 612 that communicates with the annular groove 611. The mounting post 61 is slidably connected to the limiting platform 631 through the limiting groove 612.

[0036] The limiting platform 631 and the limiting groove 612 prevent the slide cylinder 63 from detaching from the mounting column 61, thus ensuring the stable operation of the buffer structure 6.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and concept of this utility model, should be included within the scope of protection of this utility model.
